De levandes gåvor och de dödas efterlämningar : -En kemisk analys på harts och ökendadel (Balanites aegyptiaca) från två egyptiska kärl
This paper aims to investigate the embalming process and the Balanites aegyptiaca from two pottery originated in ancient Egypt. The two objects were from Medelhavsmuseet in Stockholm. Samples were collected and analyzed with Fourier transform infrared spectrometry (FTIR) and Gas chromatography/mass spectrometry to identify which components the samples contained. The results show complex mixtures mainly consisting of resin origin from Pinaceae and the vegetable oils from the Balanites aegyptiaca..
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
Tick burden in neonatal roe deer (Capreolus capreolus): the role of age, weight, hind foot length, and vegetation and habitat on bed sites
This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.
Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
(Av)slöjad : En argumentationsanalys av debatten kring ett eventuellt svenskt lagförbud mot heltäckande slöja
The purpose of this paper is to examine and to analyze the arguments about a possible Swedish law against the veil. I have therefore highlighted how notions about the veil creates and reproduces power-structures and meaning-systems. I structured the arguments in a pro et contra schedule and then analyzed them by using a theoretical framework consisting post-colonial feminism, orientalism, multi-culture and intersectionality together with research produced by Joan Wallach Scott (2010), Pia Karlsson Minganti (2007) and Anne Sofie Roald (2003). The results of the study shows that the people who either argue for or against a veil-law agree that the veil is an oppression of women and that it must be resisted. To be objective in the discussion of the veil seems to be impossible and the women it affects deprived voice.
Brunstbeteendets relation till gyltans intag av genistein
Many scientists agree that phytoestrogens could have an effect on the reproduction of an animal. The question is now why and what mechanisms that play an important role. This paper has been focusing on the estrus behavior of gilts by use of a behavioral study. Some of the gilts were given additional feed with the phytoestrogen genistein which commonly occurs in the feed as a part of soybean products. Blood samples were collected and analyzed for progesterone and estradiol concentrations.
Terminallokalisering och införande av merge-in-transit i ett distributionsnätverk för klädprover
Syfte ? Syftet är att undersöka om en merge-in-transit-lösning kan användas vid distributionen av prover inom ett klädföretag för att säkerställa låga kostnader, korta ledtider och kontroll.Metod ? En fallstudie har gjorts i samarbete med Didriksons för att uppnå studiens syfte. Datainsamlingsmetoder såsom intervjuer och dokumentstudier har legat till grund för insamlandet av empiri, som kontinuerligt har analyserats mot studiens teoretiska ramverk. Därigenom har studiens resultat utformats.Resultat - Resultatet visar på att en merge-in-transit (MIT)-lösning skulle vara att föredra inom klädbranschen på grund av de tidskrav som finns på snabba leveranser. Vidare framgår det att det är av största vikt att få kommunikationen mellan aktörerna i försörjningskedjan att integrera om en MIT-lösning ska användas.En MIT-lösning kan sänka de direkta transportkostnaderna med 69 procent, samtidigt som studien tyder på att kapitalbindningen och tullkostnaderna minskas.
Genetic diversity of Roseroot (Rhodiola rosea L.) from Sweden, Greenland and Faroe Islands
Roseroot (R. rosea L.) has gained more attention the last years, mainly because of its phy-topharmacologic properties. Even though many reports in roseroot have been published, only a few articles are dealt with the genetic diversity. The Nordic Genetic Resource Center has collected Roseroot material from Sweden, Greenland and Faroe Islands under different expeditions. The samples were analysed to study the genetic diversity study.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
Barley starch, structure and properties
Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.
Förekomst av salmonella spp hos katter i Sverige
Salmonella in cats has been documented for many years. Infection with S. Typhimurium,which is often referred to as Songbird fever, is believed to be caused by birds whoinadvertently infect cats. The disease is often seen during the springtime when songbirdsreturn from their winter habitats, while other birds who have stayed during the winter are intheir weakest condition of health. In the spring of 1999 an epidemic of S.
Seroprevalens av antikroppar mot Encephalitozoon cuniculi hos friska tamkaniner :
The aim of this study was to determine the prevalence of antibodies against the intracellular protozoan Encephalitozoon cuniculi in healthy pet rabbits. Encephalitozoonosis is an important differential diagnosis to ascending infection with Pasteurella multocida in the ears since a common symptom is vestibular syndrome. Samples were collected from healthy rabbits that were brought to an animal clinic in Stockholm for some kind of prophylactic procedure. The samples were analysed by an India-ink Immunoreaction test / Carbon Immunoassay. Of 106 rabbits 7 (6.6%) were seropositve.
Förekomst av Lawsonia intracellularis och Brachyspira spp. hos häst i Sverige :
Proliferative enteropathy (PE) caused by Lawsonia intracellularis has been
reported in horses in the USA, Canada, Australia and Great Britain. Diarrhoea
caused by Brachyspira antigen-containing spirochaetes has been diagnosed in a
horse in Japan. The presence of Lawsonia intracellularis or Brachyspira spp. have
neither been investigated in healthy nor in sick horses in Sweden. The purpose of
this study was to survey the occurrence of the two bacteria in Swedish horses.
Faecal samples were gathered from 108 foals without any clinical signs of illness
in the age of four to eight months.
Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.
Comparison of real-time PCR assays for screening of meticillin-resistant Staphylococcus aureus
Staphylococcus aureus belongs to the normal flora. Many healthy people are colonized by the bacterium mainly in the nose but also on the skin and on other mucous membranes without showing symptoms. After damage to the skin, the bacterium can enter the wound and cause infections. Methicillin-resistant S. aureus (MRSA) is resistant to b-lactam antibiotics such as penicillin and methicillin.
